Optimization of Condenser Water Loop Control in Hot and Humid Climates 湿热气候下冷凝器水回路控制的优化
德克萨斯州A&M大学学院站的中心电厂已经实施了一项冷冻水厂优化计划。由于其他研究人员得出的结论相互矛盾,因此对采用可变冷凝器水流量控制顺序的优势存在争议。使用基于校准组件的模型评估可变冷凝器水流量控制序列的节能潜力。仿真结果表明,在案例研究电厂的负荷情况下,可实现的最大节能仅为1.03%。如果计算冷却塔最小水流量的要求,则节能为负,这意味着年耗电量可能会增加3。 4%. 考虑到控制顺序越来越复杂,不建议在案例研究项目中实施可变冷凝器水流量控制顺序。引用:2019年冬季会议,佐治亚州亚特兰大,会议论文
A chilled water plant optimization program has been implemented on central plants at Texas A&M University, College Station, Texas. Due to the conflict conclusions drawn by other researchers, there was a debate on the advantage of applying variable condenser water flow control sequence. A calibrated component-based model is used to evaluate the energy savings potential with variable condenser water flow control sequence. The simulation result indicates that maximum achievable energy savings at the load profile of case study plant is only 1.03%. If counting the requirement of cooling tower minimum water flow, the energy saving will be negative which means the annual power consumption may increase by 3.4%. Considering the increased complex of control sequence, it is not recommended to implement variable condenser water flow control sequence for case study project.
